Patterns on Cranial Magnetic Resonance Imaging in Elderly People and Vascular Disease Outcomes

Arch Neurol. 2001;58(12):2074. doi:10.1001/archneur.58.12.2074

In a previous article, we used a statistical technique called cluster analysis to define 5 groups of elderly participants in the Cardiovascular Health Study (CHS)1 based on the pattern of findings on cranial magnetic resonance imaging (MRI). We labeled the clusters as follows: normal, atrophy, leukoaraiosis, simple infarct, and complex infarct. These clusters differed with respect to vascular risk factor profiles.
